UNITED srTEs 1,5,182 FLC PATENToF DEVICE CONVERTING PIPE WRENCHES INTO PIPE VISES.

Application led February 16, 1927, Serial No. 168,766, and in Great Britainmarch 1,1926.

This invention relates to pipe vises and has for its object to provide a simple convenient and portable device that permits any pipe wrench to be used as a pipe vise and is more particularly adapted for the accomlmodation of that kind of chain pipe wrench in which a lever with a cam shaped end actuates a rockably mounted V-shaped gripping jaw that co-operates with the chain to grip theA pipe the cam-shaped end of the leverV and the jaw heilig enclosed within a housing.

'Y A device constructed according tothe purpose.

present invention comprises a base adapted to be secured to a bench or worktable and provided with a slot and a bracket on each side of said slot in order to accommodate and secure a pipe wrench in such'a manner that itpcan be used as apipe vise.

Such a device is illustrated Vin a perspective view in Figurel of the accompanying "drawing,

' Figure 2 being a side .elevation shewing the device in use as a pipe vise and Y Figure 3 an alternative means for adjusting the chain. y p

Similar reference characters relate to like parts in yall the figures of the drawing on referring to which it will be appreciated that the device comprises a base a adaptedtobe attached to a bench or worktable b Vby means of the bolts or coach screws c, holes Z being provided in one end of the base ai for this At the other end of the base a are provided two upstanding brackets e and between Vthesame the slot f is'situated in the base. A slot g is also provided on the upper Vedge of each of the brackets e.

Given a device as describedl it will be obvious that in order to utilize a chain pipe wrench as a pipe vise it is merely necessary to secure the base a to the bench or work table b by means of the coach screws' c and to place the wrench, handle downwards as shewn in Figure 2, between the brackets c,

with the heads It of the pins that hold the jaw resting in the grooves g, and secure the same therein by means of the set screws lo that engagethe sides of the housing Z, the handle m depending through the slot f.

A pipe length P to be worked on may then be placed on the V n of the aw and the chain o 'adjusted around t-he pipe P.

It will be obvious that the handle m is used in the usual manner for securing and releasing the pipe P, presuming twov men l are employed, the chain being adjustedby means 'of the` nut 7'. Whenonly one man isy i i.

available Vhowever. the alternative means shewn in Figure 3 may be employed instead yemployment as a pipe vise.

vWhat I claim is :e

l. A device comprising a vbase providedl with a slot, a bracket `on each side of saidy slot, means for securing sai-d base to a work table and means for securing a pipe Awrench between said bracketsrwith the handle of said wrench depending through said slot.

2. A device comprising a. base. provided with a slot, a bracket on each side of said slot provided with a slot on its upper edge, means for securing said Vbase to a work table, and means for engaging a pipe wrench inserted between said vbrackets and securing same with its handle depending through the 1 slot in said base.

3. The combination with a chain pipe sol wrench of a device converting said pipe 4. The combination with a chain pipey wrench of a device converting said Y pipe wrench into a pipe vise,- -said device comprising a base provided with a slot, an upstanding bracket on each side of said slot integral with said base and providedVV with means for accommodating `one part of said pipek wrench, means for securing saidbase to a Vwork table, means for securing another part of said pipe wrench insertedbetween said brackets with the handlethereof depending through said slot, and means oradjust'ing the chain of said chain pipe wrench.

,In testimony whereof I affix my signature.
